Are radical and surd different?

Good afternoon dear...
the radical is just the symbol √ and the surd is the actual expression for the number, which often uses radicals. For instance, √7 would be a surd, since it is a well-formed expression referencing the positive root of x^2 - 7; meanwhile, √ is not an expression, so it isn't a surd.Surds are unresolved radicals,
such as
square root of 2
cube root of 5
These are examples of surds that are irrational numbers, since they cannot be expressed as ratios of integers.
I hope it's helps u alot .
Thanku...
